The appropriate model of the radioactive decay of a group of atoms is popping a bag of popcorn.

The key thing that we must keep in mind is that the radioactive process is "irreversible". This means that we can not turn the process around on it occurs. If it happens, then it is final.

The model that must choose must accurately reflect this observation. The only model that comes close to this is popping a bag of popcorn.

Hence, popping a bag of popcorn is the appropriate model of the radioactive decay of a group of atoms.

Jlenok [28]

Answer:

Belgium and the Netherlands swap land near Lanaye and Oost-Maarland over the discovery of a headless body several years prior, which the Belgian Authorities could not access without crossing Dutch territory. The border has been straightened out and now runs down the center of the Meuse River.[5] The change took effect on 1 January 2018.

A sample of sulfur dioxide (SO2) is initially at a temperature of 105C, a volume of 15 L, and a pressure of 1.5 atm. If the volu
Agata [3.3K]

The new pressure is 1.08 atm

<h3>Gas law </h3>

From the question, we are to determine the new pressure

Using the General gas equation,

\frac{P_{1}V_{1} }{T_{1}} = \frac{P_{2}V_{2} }{T_{2}}

Where P₁ is the initial pressure

V₁ is the initial volume

T₁ is the initial temperature

P₂ is the final pressure

V₂ is the final volume

and T₂ is the final temperature

From the given information,

P₁ = 1.5 atm

V₁ = 15 L

T₁ = 105 C = 105 + 273.15 = 378.15 K

V₂ = 25 L

T₂ = 181 C = 181 + 273.15 = 454.15 K

P₂ = ?

Putting the parameters into the equation, we get

\frac{1.5 \times 15}{378.15} = \frac{P_{2} \times 25 }{454.15}

P_{2}= \frac{1.5 \times 15 \times 454.15}{25 \times 378.15}

P₂ = 1.08 atm

Hence, the new pressure is 1.08 atm
